		Case No.	14-10475 (CSS)
		Reporting Period:	31-Mar-14
		Federal Tax I.D. #	52-2107911
Notes to the Monthly Operating Report
GENERAL:
The report includes activity from the following Debtor:
Debtor	Case Number
USEC Inc.	14-10475 (CSS)
Notes to MOR-1b:
Cash disbursements shown are based on a book basis which consider a disbursement made when a check is
issued, as opposed to when a check is presented for payment.
Amounts do not include interest on the DIP Loan, which is accrued to the outstanding DIP Loan balance.
Notes to MOR-1c:
All amounts listed represent the bank balances as of the end of the month.
Copies of the bank statements and cash disbursement journals were not included with the MOR but are available
upon request.
Cash balances include $9.1 million of Prepetition Collateral that constitutes Cash Collateral from the proceeds of ACP
Cost Reimbursements. This Prepetition Collateral was held by the Debtor until entry of a Final DIP Order, at such time
when this Prepetition Collateral would be transferred to the DIP Lender as a reduction of Prepetition Secured
Debt (capitalized terms shall have the meaning ascribed to them in the motion of Debtor for Entry of Interim and Final
Orders authorizing the Debtor to (a) obtain Postpetition Secured Financing and (b) apply Cash Collateral to the
Prepetition Secured Claim of the DIP Lender - Docket #4 filed March 5, 2014).
Notes to MOR-2/3:
The unaudited condensed financial statements as of and for the one month ended March 31, 2014 have been
prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Certain
information and notes normally included in financial statements prepared in accordance with GAAP have been
omitted. The unaudited condensed financial statements reflect all adjustments which are, in the opinion of management,
necessary for a fair statement of the financial results for the interim period.
The Income Statement reflects revenue and expenses that directly correspond to the debtor legal entity, USEC Inc.,
and does not include non-debtor affiliates and subsidiaries.
Amounts shown in the income statement reflect the full month of March, which includes pre-petition activity.
The Balance Sheet reflect assets, liabilities, and stockholders equity that directly correspond to the debtor legal entity,
USEC Inc., and does not include non-debtor affiliates and subsidiaries.

Notes to MOR-4:

USEC Inc. received an order which allows the payment of pre-petition taxes. The tax walkforward will reflect

both pre-petition and post-petition taxes, and the beginning balance for this MOR will reflect accrued taxes as

of March 1, 2014.

USEC Inc. does not expect to be required to make any federal or state income tax payments.

USEC Inc. files tax returns and makes tax payments periodically. The tax returns and related payments will be made

available upon request.

USEC Inc. is current on all post petition payments other than disputes that arise in the ordinary course of business

and amounts expected to be but not yet authorized for payment by the Bankruptcy Court.

Due to the volume of activity the detailed listing of aged post petition payables is not included.

The post petition accounts payable reported represent open and outstanding trade vendor invoices that have been

entered into the Debtor's accounts payable system and does not include accruals for invoices not yet received or approved.

The $323,000 credit shown in State & Local: Other Income was received by the Debtor and represents a cash

payment received as a check, and was not credited to the Debtor's cash account until April 4, 2014. As a

result, no cash receipt was included on MOR 1a or MOR 1c until the deposit is actually credited to the

Debtor's account.

Notes to MOR-5:

Accounts receivable represents amounts due from the Department of Energy (DOE) related to the

Research, Development and Demonstration (RD&D) program for the American Centrifuge Program (ACP).

Notes to MOR-6:

Interest expense on the Debtor-in-Possession (DIP) Facility and Secured Intercompany Loan are accrued

to the loan balance and do not result in a cash payment.

Notes to MOR-7:

USEC Inc. has received orders that allow payment of pre-petition taxes and certain pre-petition liabilities

such as employee benefits and employee expense reimbursement.

The DIP Lender is the Debtor's non-debtor affiliate, United States Enrichment Corporation subsidiary.

The Debtor allocates corporate overhead charges incurred to its non-debtor affiliate, United States Enrichment

Corporation. As such, the Debtor is allowed to apply the monthly allocation against the outstanding DIP borrowings.

As of March 31, 2014, the Debtor has approximately $2.5 million of allocated corporate overhead outstanding

that will be applied against future DIP borrowings.
